// Logger is the logging interface used throughout the library.
// It is compatible with *zap.SugaredLogger out of the box.
//
// Usage:
//
//	// With zap:
//	logger := zap.NewProduction().Sugar()
//	adp, err := binance.NewAdapter(ctx, binance.Options{Logger: logger})
//
//	// With NopLogger (default when no logger is provided):
//	adp, err := binance.NewAdapter(ctx, binance.Options{})
